Doesn't seem gigantic to me...you've removed anything that we wuld have to compare scale with.

Take a look at the pond's size, I don't think the horse would have taken all that place if it was normal-sized

Perhaps you see it author, but honestly I too am having a hard time seeing how supersized your very cute colt is. Maybe you could add some trees, just a suggestion.

Thank you EmiK, i'll do that asap

It's too dark without sufficient scale comparison. Whatever it is in the lower RH corner isn't clearly identifiable and the top of the horse is almost impossible to distinguish from the clouds. There's also a very noticeable white edge around the legs and backside of the horse.

Updated. Thanks for the suggestion, EmiK

That looks great, glad you were able to make the changes. = )

Great artsy look.

I've seen your previous one, and I too could not see how you supersized it, but it is a lot better now. I also love the texture you used. Very nice

great work...well done
