Hi, i`m not sure how can people help since you posted one single image, also what do you exactly mean by "some help" ? Explain how to help you ?
So far, i could critique this image :
- what catches my eye at the first place are those white spots, i suppose it is mist, they take too much attention from the character, themist should be more "all over" and subtle
-maybe to do some reflections of the lights on the water
-enhance the shadows and the highlights for more contrast
-the form of the tail does not read very well, thats about values ^ - ^
I like the colors, the idea of the character and the environments looks good too as well as the composition.
Anyway, this is just my humble opinion wich is not necesarely correct for i`m not very good at art
You should post more of your paintings for a better vision
