Hi Calvin, we really need some better pictures (in front of a blue background, in natural light such as under a pergola/veranda, camera on "macro" settings).
From what I can see you have given this a fair crack, for a 1st.
It is great that you are willing to go to "mother nature" for your diorama material, something, for some reason, many modellers are reluctant to do (hey, you can weed the front patio and collect dio material at the same time!).
Good effort with those figures, shame you spilled crap all over them! I recommend that you post pictures on Historicus Forma as you progress, as that's where many of the hobby's finest figure painters hang out.
