You are great. I also had an idea for a Farfetch'd evolution. I'll be adding it to my gallery soon. I think your coloring is great...especially compared to mine. Mine is more of a knight than a samurai.
Concept is really good, i had quite the same idea (mine has different body but exactly the same face!!) but mine remains on sketch book.. I think you can do better with the coloration... Shadows on the orange part are not completely visible cause are very similar to the original color and it seems you forgot to lighting this part.. anyway that's a very good beginning!! continue practising!!!
