I'm afraid I have to agree. I love the enthusiasm, this is what I'm missing sometimes here! But a model like the Psyco will take forever to complete, even if you rush it - but if you do, you'll be unhappy with the result. At least this is how it is with me. Don't forget that the crooks multiply - if one piece doesn't fit, you cannot glue it well to the next, so the join gets crooked too, and so on, until you get a big gooey hunk of cracks.
Take your time. The pieces you threw together in two days would have taken me at least a week.
When I started, I thought that it would take like two days for a simple gundam and maybe two weeks for a big one... boy, did I learn. Multiply that by at least 10. It's a shame really. On the bright side, papercrafting taught me patience and thoroughness.
So as much as I'm inclined to see where it's going, I'd start over with an easier one, with 100 parts at most.
I see you're in Germany (I buy at Rewe, too): In case you don't know yet, don't use UHU! I think the awesome highness it causes is an important initiation to the mystery of papercraft, but it makes you so high you'll screw up royally. Get Bastelleim, it makes less stains, it glues better, and it keeps you in operable mode.
