Being a artist is difficult why becasue you wanna make everything look perfect, and you yourself never think your art is good no matter what others say. Being the artist that we are we tind to get a little over perfect and get frustrated at certaint drawings. I can say from personal experiance I will go days if nit weeks withough drawing becasue im so made about not being able ti get this one thing right, but in all my years of art i have learned pactience is key. If you cant finish something right away either go take a nap, or do something else. Now im not saying give up on it but what i am saying is that with drawing, painting (models or art) or even making things on programs like 3d modeling, photoshop, etc. Its best if your stuck to come back to it fresh and with a new perspective and sometimes that can be achived by preying, stepping away, taking a nap, or even starting something new.
