nice pic. i the arms look crazy like that. soo long. i think for composition you might have wanted to flatten out the bedsheets a bit. and maybe the other cat could cuddle up with the one in the front or some a bit closer. for me solid borders of one color are enough and if you want that black line between the border and picture i usualy take 1px width for it. i think bigger looks clumsy but iguess its taste.
