I love what you have done with oldale and littleroot, they are nowhere near as bland as they were in RSE., your tiles are really good, and the rectangular shapes i think suit hoenn. In short you are a really talented... tile-maker?
My only criticisms are:
- theres something about Proffesor Birches roof that looks a bit odd. Im not sure what but it looks a little flat.
- The frame on the pokeball symbol looks a little high, im not sure if that is accurate to HGSS style or not but nonetheless it looks a little out of place.
Since you are doing requests, how are gyms coming along? are you updating the RSE style or using HGSS like the pokemon centre and market?
