Comparing pieces

Didn't really think much had changed in my style, still have days where I cant get as detailed as I want and other times it comes really easily.

The critter design can be found in achaemenid architecture, one of the lion pieces. 

Colored one is from 2012 and when I tried to get back into drawing from a bad artblock at some point and looked up different mythological creatures to try my hand on.
Not my best work from that year tho and the sketch beside it is now from 2014, with another retake on the same creature.
