^ I believe we agree. It is fully up to the artist. So, why a WIP? I would think it was posted as a W.I.P. seeking to generate enthusiasm, participation and therefore opinions/tastes are naturally expressed.
I don't think essorant just wants "ooohs and aaahs". He's a Master Skinner in every sense, as you are, Tim. He has the final say, and that's understood by all from the get go. Start Buttons? I think they're a major part of the skin's 'personality'.
I wish there were a library of Start Button graphics to use as the skinner wishes (with appropriate credit) with modification or not....I know there's supposed to be one at dA....at least there was a post about it some time ago. Maybe there should be a Start Button Contest? Why not?
I understand the commercial aspect, and respect it. So, shouldn't an artist listen to his audience/fellow community members?
This WIP concept isn't just advertising: It allows artistic participation for non skinners and that's a good thing, imo. I believe it encourages people to be more active. The more the merrier, as long as it's in good taste, and done respectfully balancing likes and other feelings. Words should be carefully chosen.
That's only my opinion though, and everyone is entitled to his/her own. I don't think any creative process should be stifled...quite the opposite: It should be encouraged, supported and shared. Isn't that part of "Community"?...well, I hope it can be.
As Harley says, "Skinner fuel!".
