Daniel, that's absolutely beautiful! Blows my cruddy sketches out of the water.
I really didn't expect such an enthusiastic response, lol.
I'm up for doing requests, definitely. May take a while though, I have a lot going on at once, and an exam coming up soon to boot. But I'll definitely make a go of that cabinet, and try the Obsidian sword too (that one's going to be a challenge!)
Btw, here is some info that may help others wanting to do the same. I use Photoshop CS3 - which isn't free, but there ARE free art programs out there, most notable of which is 'the GIMP'. It's quite powerful for a free program and I encourage you to check it out. It can save files in all the popular formats.
For actually drawing the images I have a Wacom Intuos art tablet. It's brilliant, I've had it for a couple of years now. The pen has never needed replacing, it doesn't use batteries, and is nice and light - about the same weight as your average biro. The tablet is pressure-sensitive and can be configured to be firmer or softer, based on your preferences.
I suggest saving the image as a JPG with 80% quality (or less, for larger pics). You should aim to keep any single image below 1 meg in size.
To upload the image, I recommend "imageshack.us" because it's quick and easy. It rarely goes offline, but sometimes the site can take a while to respond. Just to go the site and find the file on your harddrive, click Upload, and all the links you could possibly need will be generated for you automatically. The one you will probably want will be "thumbnail for forums".
That's about all I can think of, hope it's useful.
