Wow your right about some new drawing techniques and hell if it keeps up these sexy MLP works than please do keep them up!
Hats off on the work with Mrs Cake, amazing that even the smaller ponies are getting their attention from the show too and despite what thought about her you've really blown me away on your deliverance of epic booty here.
The anthro version you've cooked up is quite an appealing piece of work, still sticking to the nature of the show in most manners when doing the legs and hooves but still adding those small touches to really define that sexy female figure, well done.
Great use of the darker shade of blue for the outline though, gives her a really softer appeal and that can be especially said to that nice pony booty, hot damn!
Lastly hats off to the work with the eyes making them so lush and gorgeous to look at, plus the little touch of shading to really help round out that pony bust, smooth work rayodragon.
