I have that model. The good news is that it was free as a KS stretch goal (D&L has very good stretch goal rewards - the same campaign also had a fantastic tarrasque as a SG reward!). The bad is that I was pretty happy with my paint job until I saw yours. That looks fantastic and you'rre not even done!
Also, I think the base is too small - it's a huge miniature on a large base. D&L initially did the same with the sea giant in the current campaign, but changed it after some of us pointed out the mismatch. I agree that there's nothing that screams "giant" about her, except the size of the model. Cloud giants are generally not that unusual looking, but it would be nice if there was something - I think Wizkids does a pretty good job of making theirs distinct.
