Hello Daniel,
Patience my son, some people are a bt slow... me included.. :-)
I'm not familiar with the Hasegawa kit, but I would guess it's an older kit?
Most of my observations would be issues with the kit, not your effort. It looks from the pictures that you did a good job construction wise, and your initial paintjob looks good as well, which paint did you use?
I feel you have 'over-weathered' a bit, that's easily done, It took me many tanks covered in mud untill I finaly realised that 'less is more'. It looks like a heavy dry-brush on my screen, something which, especialy in a small scale, you should keep to a minimum.
Other things are a kit issue, such as the tracks, and the vision ports on the turret side walls. They should be further forward, basicaly where the turret no. is now.
My tips and suggestions? Keep at it. You improve with each model, and learn something new along the way. If you want to stick with 1:72 scale, try some of the Revell kits. They are cheap but good, basic kits that are great to learn with.
You say you're new to Armour, what did you build before?
Cheers
Henk
