I've recently got photoshop elements and I want to try colouring in one of my hand drawn anime pictures. I know i haven't got photoshop Cs4 which is recommended but i couldn't afford it
So would someone give me some tips on how to colour it in so it becomes like a professional picture?

Ps. I'm pretty new at photoshop so tips in simple english are desired

If you've hand drawn the sketch/lines, create a layer on top and set the mode to multiply and go from there. There are lots of colouring tutorials on deviantart.com
Good luck!

Becca got my vote for her very good answer. I'd just like to add a couple of things about the PaintBrush Tool. When you click on the different tools in the toolbar, you'll notice that the thin strip of things right above the workspace changes. This strip is the Options Bar and it's different for every tool. For the Paintbrush Tool: Over on the far left side is a little arrow. Click this and click on Reset This Tool if the Paintbrush ever starts to act a little whacky or if you've changed the Brush Options and need to change them back. Over on the far right side is what looks like a pretty icon of a paintbrush. Click on this to get the Brush Options dialogue which allows you to change a bunch of brush settings. If you change the Brush Options or if you use a specialty brush you've downloaded and then switch to a "regular" brush, don't forget to reset the Paintbrush Tool. The little arrow between the Airbrush icon and the Brush Options icon hides the Brush Tablet Options that you need to set if you're using a pen/tablet to draw and paint. That's all.
