On that subject, I've got a handful 'o tuts on my freebie Geo site if you want.
No creatures I'm afraid, just simple things.. but the subject isn't necessarily that important, still serves to get peeps familiar with some of Wing's tools & interface. And they're mostly written in an almost "script form" (e.g "Right Click > Extrude to 0.5, then Right Click > Scale Uniform up 200%" etc.) so very newbie friendly, with pretty much all the steps anyone could need.
Maybe skip the pumpkin tut... it's is the oldest, and the hollowing out part could be done easier with the 'Intrude' command (which wasn't in Wings at the time the tut was made) rather than how I did it there.
The mushroom one is pretty good 'n current though, biological-ish modeling.. and touches on tweak-magnets which you'll definitely want to know about for animal modeling.

I'll throw in some Wings3D fan-boy support too :} Everything (3D) in my gallery was modeled in it. Just a small free download so got nothin' to lose in trying. Only does modeling and texturing however, so would have to rig, animate, and render your meshes elsewhere I'm afraid..
In any case though, as this will be your first modeling experience it will definitely take a while.. If you already have a good '3D mindset' (even a good 2D painter needs one really.. volume, scale, perspective etc) then might grasp some things faster, how to get the good volume/form into the model, and have it look right from all angles rather than just front/side etc and other beginner pitfalls. But beyond that you'll also need to make the mesh all pretty with a good natural flow to the geometry and such if you want it to deform well (said wanted to animate).
Still pics are easier, can always "cheat" a bit, adjusting things by hand if the 'pose' you put your creature in doesn't look right (sculpt it "for the pose" as it were), where as with animation that's not really an option.. So I'd guess anyway, I don't animate myself yet, still at the cheating 'model for the pose' stage hehe..

P.S 'eh Teyon "Try the programs in the header or try WINGS"
Why ISN'T Wings listed in the header with the other freeware apps? Have always wondered about that whenever I venture in here.. sacrilege!

Hmm.. not sure how (or even if it should have, since didn't seem so "dark") bodger's entry got from the funniest category to the general one, but well deserved anyhow. Was probably my favorite entry as well, nicely done. Congrats to all the other winners as well.. No such luck for me it seems, a month 'o work for naught :[ Ah well, didn't fare much better in the last Halloween contest I did here, guess I'll take a hint. I shall now go away and stew in bitterness and bad sportsmanship.. so there! :P

Same as nelip's was linked at Suurland.com (the actual linked URLs didn't work, had to edit out an extra id tag that was screwing them up, but should be able to figure that out heh)

Anyhow, here's the other variants available..

Was wondering where the hek all the R'osity forum traffic was coming from since I didn't see anything in the Wings3D section. Finally tracked it down, now I can rest..
Sorry.. kinda compulsive about this stuff, just ignore me hehe :P

Oh.. err.. Nice mushrooms of all kinda above there everyone, good work.
Runs off back to the Wings forum

Hope this isn't too late, I don't usualy check this forum.
I registered with Eovia a while back (had to, to download Carrara3 demo)
And I got an e-mail from them with a special holiday sale until December 4th

there ya go

unless of course the special "cupon number" is exclusive to my registered name.. In which case that's probably worthless. Maybe you should register with them and request their e-mail letter thing. To get 'em to send you the same offer

I couldn't access the site all day yesterday
got a SessSQL: Too many connections error whenever I tried..

And Im in the U.S
