Nicely done. Like the tree and the base. Good groundwork. Good presentation base, doesn't compete with the kit for attention and shows it off nicely.
If you are going to photograph outside like that shoot early in the day so you get a nice even illustrative light, or wait for it to be a little cloudy or overcast. Direct sunlight casts some harsh shadows. You could pick up some white illustration board and position it at an angle around the tank out of frame. This white surface will reflect light back onto the model and fill in the areas that are now cast in heavy shadow. Its a soft light and it makes for nice illustration work on the piece being photographed. Otherwise you could get really elaborate and make a photo tent (doesn't have to be big, just enough to cover the area or table top you are shooting in) from thin white fabric that you can set up over your model and shoot under it. Again its a softer, more even light that is bright enough to shoot but soft enough that there are no harsh shadows thrown.
Which kit is this?
