After six weeks (on and off evenings) working on this, I think I'm finally finished with the modular assets part of the Tower Defense Course, ready to move on. I wanted to get stuck in with this course because I knew it would be a challenge - other than a few months modeling, every other aspect was new to me! I learnt an awful lot following these lessons. In hindsight, I'd love to be a little more creative with the style. I particularly struggled with the Photoshop elements but practice makes perfect ay! Overall I'm pretty happy, I have some assets that fit together well and don't look too bad!
