Adzerak's book o' sketches

[clockodile]

Man that golem picture looks awesome, the scale and the camera angle ramp up the drama really well. I think you could take it pretty far if you were so inclined.

Wet skin is tough to paint. Usually there is some form of strong highlight from the reflective water, and because the skin is greasy, droplets tend to separate out a bit and cling on, creating dots. I recommend looking at lots of photo reference, because the result is rather variable, and as it is overcast, the reflections would be softer than usual. You can get some fun effects with this sort of light though - like occasionally the raindrops splashing on a surface will create a subtle glow where the light scatters through them as they break up and bounce off.

With regard to the rest of the picture, you might want to ramp up the ambient light intensity somewhat, since those clouds would be scattering a lot of cool light all over the place - you already have the colour temperature working well though. The colour scheme on the whole has a nice natural feel to it, well done on being brave with the reflections in the puddles too.
