My two cents worth....
From an outsider that is a hobbyist, it makes sense that if you wish to get recognition and build yourself into a commercial artist. You will need to start small and then take on bigger challenges later once you are established. All to often many dream big and end up falling on their faces.
Many have previously put forward excellent views and points in this subject and I would assume their knowledge in this area is well worth listening to. On a matter like this, it is always best to listen to the experts.
Nothing worse than an ill prepared agreement..... learn from others whom have already been down this road. I wish you well and would like to see how this pans out for you. Good Luck!
