You should still use edge loops in anime models. It keeps it clean. (Well, it helps me keep it clean, I wouldnt know for you.)
Honestly, I dont like it very much, maybe you should work on it until you have the whole upper body completed before creating a thread.
Anyhow. The model looks a tad too pointy from the top, bring some of the verts on the side of the model foward, also, you should think about cuting some edges around the bottom the the eye then moving em forward, you dont need to, but I would say it would look somewhat better.
You using any references? Or just going off your head? ([Never mind, I didnt see your thanks david part]Hmm, since your changing to piccolo, you would either need new references... or go off your head, why dont you just stick to cell?)
Well, thats the cell ref your using? Well, (Just go back to doing cell ;x) If your staying on him, you can see the on the side the eye should be further foward.
Id like you to make this your best model so far ;]
