well been playing around and try to come up with basic flow and this is what i cam up with... i can't remembere each little step but the gist of it...
and what i did
1. dupli layer
2. then i did a catus selection and copy and paste to a seperate layer
3. i also on the dup layer i remove the catus left a nice blank area which i filled with a blue color there other ways to do it but that the way i did...
4. then then i used healling tool and clone tool to have the whole sky look as one..
5. then i worked on the catus layer.... i used primarily the transfrom tool to make the catus smaller .... and yet at the same keep the base of the catus where it looked ok at the bottom as far as width...
6. then i did a copy and paste on one top of the arms and put that on top of the catus so it would have top... flat top wouldn't look rights.. smiling...
basically it.... many times just take patience and trial and error on what works best... now the image is far from perfect it still has lot of little work on it...
there still a hint of blue on the catus... and playing around replace color or one of the other tools to eliminate that blue tint... but you get the idea.... i don't if it any better than yours but this what i came up with
