I think it would be a good idea to provide a little more info on your project. It's understandable that you do not wish to divulge too much in its current state; however, it may be difficult for some to find an interest in something they know nothing about. For those that may not be able to dedicate 100% of their time, perhaps you could estimate how many textures you will be expecting to need. Will you be needing models, what style are you going for... basically everything on this
form. Personally, I wouldn't apply for a job if I didn't know what it entailed.
