Hi Mar6874. Looking good. Nice angle to see the action.
I see you have added some deatil to the bushes, but maybe needs some more. The thicker branches that are clearly visible could do with some brown or grey colurs to show branches and maybe a little variation in the green colour. Dry brushing darker colours from the bottom toward the top and lighter colours and maybe some yellows or browns from the top towards the bottom. The brush doesnt need to be dry really as the plants are quite fragile, but just to break up the one tone. Some patches of static grass spread around would add alot as well. Some debris like a few rocks or a twig to represent a fallen tree could also be cool. The actual earth looks excellent ... what have you used here?
Sorry to reign heavy, but Im hoping to help a little. The figures look really cool and the story is conveyed which is the main point. On the link you have given there is only one blurry picture ... is this the right link?
Anyways .......... excellent little dio and with some extra attention, which is still quite possible to add you could have a little stunner!! Good luck!!
