You've got some great artwork, but the display method is killing it. :\
You want people to see your art in the best way possible.
- Try to get more picture and less 'other.' Crop out all the extra stuff so your art can take up the most space, and not have to compete with the cat on the desk, your DVDs on the shelf, or the underwear on the floor that wasn't supposed to be in the picture.
- Set the picture and the camera so that you're taking the photo straight on. This gets rid of angle distortion.
- Have enough light, but not direct sunlight as it can be too bright and fade detail. Filter the light so you have light, but not shadows or bright spots.
- Be aware of size. At normal size, this looks good. But when brought up to full size, this is so big that it's hard to take it in. If my monitor is at 1024 tall, then 2448 makes it so only 40% is able to fit onscreen, for example. I set mine at 1166x845. That's what size they came out, but it wors wwell, as you can see it at normal size, but at full size, nothing is lost outside the edges. Some outside is ok, but too much cuts out the art your worked hard to make.
- Use a scanner. That's how I got mine in. It was set at 150 DPI (I think) and then I still cut down the size by about half. Then, I ran them thru Photoshop to get any colored pixel noise out.
All my pics came out of a book just like this. I removed the pages so they could be scanned. Yes, I had to be careful when removing them, and they were problematic to get back in until I figured out the easy way.
Your artwork is good. Just be aware of what else is in the picture as well, and try to get lots of the art, and less of the 'stuff.' :)
