And please, i saw many good made games go down to sewers, because of multiple of reasons, but the horrific one is this: hard drive go down, and go HARD, so you lose everything.
Also take a rest sometime, to not burn down, i dunno what is in the artists area of problem, but developing a game you love as your art is good, but i saw few guy almost saying that they are shit, but they are not, for large number of people, so if you feel down, ask and help of an expert, and remember, your health is priceless to you only.
