Looks great M. I think perhaps you're using flash? That'll kill some of the detail, which is why it's not that clear. A good outdoor shot, or under a good lamp, should do the trick. Adjust the 'white balance' accordingly for the latter.
Not bad from what I can see, just keep it tight and not too dark along the panel lines and if it isn't quite right you rub it off and go again, that is the beauty of the pastels!
Took this one outside this morning, its a really dull overcast day here today so the flash went off. But I think its a bit clearer that the pic I took last night on the bench.
