Well, when it comes to requests, the people giving and receiving them should view them as what they are, gifts. You're by no means obligated to do them and people have no right to get upset with you if you decline their request or aren't able to do it in the end. It's like getting upset that someone gave a present to the person sitting next to you instead of you and throwing a hissy fit over it, it's really silly.

But really, if you'd like to take requests you should feel more than free to do so, your art is amazing and taking on some ideas from others can always be a nice way to practice new things and characters. Just don't take too many at once and give yourself time to rest and work on your own projects as well.

I personally would love to request something from you, myself~ I adore your work and if you do decide to open them up in the future I'd love to ask for one from ya if you wouldn't mind.

Also- (I forgot to respond to this earlier) As for art trades, normally one person asks the other if they're interested, if so then they both come up for an idea for the other person to do that will normally be around the same quality as what they will be asking for (Sketch for sketch, full picture for full picture, ect.) And then once everything's sorted out and both agree each person simply works on the picture and gives it to the other person when it's done.

Oh so that's how it works. Sounds fun, but I am not ready for that type of commitment. '^.=.^

Just give it time, and when you're ready for it I suggest maybe try trading with someone you know personally a few times first so you can ease yourself into it~

You're right. I shouldn't feel so bad about it. It's just this damned personnel guilt I keep throwing at myself ever since last time.
This time though I'll try not to beat myself over it.

You shouldn't, requests are gifts from the artist to the person who asked for them. If something happens where you're unable to complete the picture, or if you simply decline their request from the start for one reason or another, that's completely fine and they should understand. If they don't, then it's their problem, and they're in the wrong, you shouldn't have to worry about anything.

And Suhayll, my memory's horrid so I can't rightly recall what happened previously. But whatever it was don't let it weigh you down. Everyone makes mistakes and you're only one person, you can't do everything and everyone learns their limits through trial and error, it's how we learn, and it's part of life. Just take it slow at first, maybe like.. three requests and do them on your own time whenever -you- feel like working on them. No time limits, no obligations, just fun practice that will make someone's week when you've finished with it~

Just don't push yourself and have fun with it, alrightys? *Huggles* =3

 Rottin stated my thoughts exactly.

You're only one person and a mortal being at that. If someone expects perfection from you, well then they have some issues. Don't let it weigh you down, Suha, I've been down that path many times.

 rottin said it perfectly , I would honestly love to get a request from you, your art is really nice and cute. But again people might be jerks with the whole process and not be grateful or impatient or Ect and honesty I just block those people.

Tldr: yes you should because you're a cool dude
