Hey Congrats on finishing term 2, I myself have only completed Photoshop 2. Im currently working through Perspective 2.
Anyways i just had a bit of feedback for you regarding Photoshop 2.
1) Your logo is really well done.
2) Alien Looks Good, a bit to big in my opinion but good overall.
3) for the box cover it was well done but it look a bit choppy at the top (might want to consider cleaning that up) also the box cover seems to have a perspective issue. ( the orange line that travel vertically looks like its a part of the front of the box in the top and it looks like it becomes the corner at the bottom.
4) regarding the color blending exercise it looks like there is a big discrepancy from color to color, try to not put as much pressure into the brush strokes so that it creates a come seamless transition from color to color.
