I don't usually make concept art and you can clearly see it if you take a look at my models. One model that has specially suffered from this is the mutant model that has been remodelled twice with bad results.

Now, I found a great mutant and alien artist who has made me a concept for the mutant and I'm going to remodel it once again. Sadly, the actual concept art was destroyed and I have only a sketch that should do well for now.

Modelling under way.
