I'd say your art shows a lot of promise, especially from the fact you're in the early stages. A lot of webcomics start off in a very shoddy manner artwise and evolve, so I'd be interested to see how far your stuff evolves from this already avdanced looking stage.
That having been said, constructively speaking, I think you need to work a bit more on the premise. The webcomic "market" is incredibly flooded with "gamer" strips and you'll have a lot of trouble catching much of any attention with stuff like C+A+D, Penny Arcade and PvP already grabbing the niche by the balls. If you can come up with a really clever twist to the genre, you could possibly go far.
My other advice to you would be to plan out significantly further ahead. Five strips is minor headway at best. You don't want to run the very dangerous risk of running out of ideas. If you base it TOO much on your personal experiences, you'll end up sinking on a boring week of your life and run across a lot of cliches. I'd recommend taking a weekend, or perhaps even a full week of evenings, and plotting out a rough outline of your first year. I'm talking very rough. Like, sit down and plot out a bunch of potential story-arcs and where exactly you'd like to see it go and evolve to. Once that's done, you'll have a vague idea of what you're building towards. The beauty of that is, there's no harm in throwing in a one-off gag here and there.
Also, write down every single good idea you ever have about it. Keep a pad and paper on hand at all times, basically. There's no such thing as too many potential story points.
Also, something I've seen work for a lot of writers: never, ever, ever, EVER take advice from your readers once you've got it up and going. Stick with YOUR storyline. If you deviate too much into other peoples' suggestions, you'll meander from any basic plot you may have outlined. A quick suggestion here or there for something minor can work, but fan service can ruin people.
I'll probably have other snippets of advice I'll edit into this post if I think of them. I actually considered starting a webcomic with an artist friend a while back (I can't draw worth a damn anymore), but it never went anywhere and our premise blew.
Like I said, though, your art shows a lot of promise and it's definitely unique to other stuff I've seen. That's one of the most absolutely important parts of the process and you've got it down already. Just do a bit of tightening on your premise and do a lot of heavy forward thinking and you could have something here. Good luck to you.
