The pleating really looks good. Overall, you've done quite well, and, yes. there is a lot of tartan!

I would suggest the following as adjustments for an even better look when you dress up (as opposed to going for the ren-fest look). It would require a doublet or something to which you can pin the extra material on your shoulder. Don't pin it to a shirt as it will pull and/or tear your shirt. Here I am talking about bringing the whole thing up in the back instead of part in the front and part in the back, brooched together.

1. Shorten the bottom/lower the belt. The selvage should just touch the top of your knee cap.
2. Adjust it all in a mirror to make sure your "hem is straight." I've found that the hardest part of wearing a great kilt is getting the bottom edge straight so it doesn't look crooked and really tacky. You seem to have done quite well in your picture.
3. Go here to try out several ways to make it look good (start at #12): http://www.theweebsite.com/greatkilt/index.html I personally like to see a long drape in the back with just a bit of the corner left haning down for good effect. (Sharpen the pin on the brooch so it doesn't leave a huge hole in the material or your jacket.)
4. I use a military web belt to hold the kilt on me and then wear a wide leather belt for show. The web belt cinches tight for holding everything in place, and it doesn't show under all the tartan material and the kilt belt.
