our first dev is very busy but he also stopped doing that kind of art because he thought it was "not good enough".
I always liked it, but artists can be like that, they see imperfections and want to improve while for another person it could look great. we changed to another artist for awhile, but he also got busy, so now we have 2 other artists working and many of the old CG are updated to fit the style. the 2 artists we have now their style are similar so it works well.
not sure u meant the 2nd artist we used for awhile, he tried to make it look like the first artist, but its not easy.
but the last 2 artists and quite good if u ask me but the art-style is different.
