Let him do what he wants and needs to do smiles XD
In all seriousness though, for you barely drawing pony characters, they look much better now than the first time you drew them. Your art has improved just in the last few months, and it's gotten a lot better since the beginning of your KUWT comic. I'm glad you draw what you want, and it's kind of you to offer commissions like this
Headshots/faces are some of my favorite things. They're literally one of the few things I myself know how to draw, but more than that it takes time and effort to make a face look different than the usual smile or face expression.
I love masterXtreme's comment. Short but very clear

There was a lot of effort that I can see put into this commission (or commissions, I don't know XD) but seriously, I'm glad people here besides Kyrl or the people on DA noticed this commission.
*people, pay him XD If you want more, pay the price

he needs the money.*
Also, Smiles, your comment is adorable.

It literally is something I can see that icon picture of yours saying.
