ha ha :) Air brush extravaganza :) Fun fact is that even if you do it in easy way if you place light and shadows correctly and keep edges sharp it looks good - and bigger model = better effect with air brush point is to not fick up contrast in light / shadows and in colours - rusty base is good clash for this blue / green theme chers :)
If I may offer some critique, even though I am not nearly as good as you: It looks like you overdid a bit with the pigment where models touch the base. These are the places, where shadow falls naturally so they should be a bit darker, but on presented models, they are particularly bright because of pigment accumulation. In case of the TAG- to the point that it is a bit distracting. Other than that, the models are obviously beautiful and I love the composition
Mmm well, yes I understand you and will be correct, but I decide it to made more strong the contrast, just under artistic view :)
Sure, that is definitely your right as an artist! :) Please keep up the good work and post more pictures of your models.
