If you recieve only a few votes (less than 10 or even less than 20) then it is a matter of luck if picky or not-picky people stumble upon your work.
 
More votes (like 30+) give a more accurate picture, and the rating is less sensitive to luck and randomness.
 
I recommend drawing for enjoyment, and drawing a lot. Focusing on downvotes will only make you draw less, and enjoy drawing less. Creating fanart is meant to be fun. Don’t ruin your own fun by focusing too hard on downvotes.
 
 
And if you just want upvotes, then draw fanart for other artists who don’t get many votes. They, just like you, like to be noticed and appreciated for their work.
 
Also, it is easier to enjoy work based on existing characters (who bronies already know and like) than OCs (who are total strangers to the viewers, and it is hard to care about just some stranger).
 
Draw a lot for fun. Only upload the things you really like. Improve, even if slowly. That’s the best tactic.

I know it’s not really high quality, but…  
Why so many downvotes?

I think a couple things I could improve are Merlin’s face and Shade’s hood.  
Uh… Any other suggestions?

Pinka’s cap+hairstyle+ears and Shade’s eyes+hairstyle+hood+scarf look best.

Notice how each character also looks like the pony that’s playing them.

The way I see it, roleplaying sessions will typically have players imagining themselves in the world as their characters, and we the viewers have the luxury of seeing that fantasy for ourselves.  
At least I remembered the gist of what each of their characters were…  
Including Pinka’s bagpipes. :D  
Oh, and this is also my first time drawing an orc.

My imagined versions were uncreative stereotypes. Either as humanized ponies or standard-looking drawings of races you might find in a D&D manual. Your drawings avoid that mistake of mine. :)
 
I mostly imagined ponies sitting at the table when writing the scene, not their characters.
 
 
…speaking of, while I myself have no complaints, I can perfectly see RD complaining that Doombringer is too cute for the KILLING MACHINE he is. XD
 
And then the rest of girls tell her to shut up and politely say “thank you”.

@dziadek1990  
Do they look accurate enough to you?  
I honestly had to wing it on Doombringer…  
Glad you like it!

As my beloved Jim Carrey-sensei would say:
 
B…E…A…U-tiful! >:-D

Wow, people actually like my art for once…  
Thanks everypony.

Alright, the upload has the correct link!
