Here we have a very interesting concept, executed on a very cool skin from the TFT roster.
We have 3 variations here, all done very well to transform the Sea Giant into something completely different. The style is cartoonish but has great shadowing and highlights and the unit is completely transformed. Particularly the arms and where the coat folds into the belt is done really well. The face also has a very different shape and the unit as a whole blends in well with the style of Warcraft which is cool.
Areas for Improvement:
In terms of the style it works really well and you've honed your own unique look. The only thing I could suggest would perhaps be more variation in texture work, you've got hair and skin and the bright blocks of colour down but maybe in the future you could look at trying out other styles. This is less of a criticism and more of just a suggestion for you as an artist.
A really cool and unique concept for a unit we don't see often. Its got good highlights, colour choice and design that all comes together in a skin that definitely stands out. It also comes with variations and icons. Therefore, I'm going to approve this as High Quality.
