IMHO we all create the odd horrible pic!!! thats where the delete button comes in soo handy...... but there are some great learning resorces out there for you.
Check out geekatplay.com if you havnt already, their tutorials are the best!!!
Keep plugging away, look at other peoples work, troll the forums for ideas and fixes and take advantave of the tools that are avalible with vue.... things like skin vue, terrapak, the swarm, and interor pak to name but a few.
And dont be discoraged and think youll never be as good as some one else, some of us still feel like that from time for time that have been using vue for years!!
Develope your style, and stay true to what you want to create, and if the results arnt what you want, then try to find out why..... some one out there will be able to help you!!
Ve & ins a great tool. but start with what you feel comfortable with, then move on when finances and inspiration dictate it!
