Very nice job on this. Pretty much the whole thing looks cool. I like that you added the green hill to the foreground, which really helps to balance this out and give depth.
Accordind to this you actually have 35 colors, which is over the limit of 25 for this contest. Did you used a brush with less than 100% opacity or reduce the opacity of any of the layers? Let me know if you need any help with this.
Thank you so much. I didn't use a brush. I changed my mind, i'm not going to participate, it's just a training.
