In terms of composition and colours you've nailed this.The only thing missing is that you haven't chosen a point to focus on. It appears that the the the creature guy further away is telling the story in the image so my critique would be to eliminate that blurry-ness around him and the little guy he's pointing at, define those edges around them and as a result should hopefully make them both pop out in the image as a focus point.I just got told off for not meeting the minimum word count for this so I guess the only other minor criticism is the grey smoke coming out of the crashed ship. Because the image is so vibrant and full of colour the grey smoke feels a little out of place. In real life it probably would be that colour but for illustration purposes I would make it more orange/yellow so that it works with the current colour scheme in a friendlier way.Here's a little visual aid to demonstrate: [link] Other than that, great job!
