ok well either way besides on the place for finishing this up, I still need some ideas for the rest of my arm or what would look best

I go to this place called GoodFellas, they do really good work, but I need ideas as far as what to put on the rest of my arm to make it a actual half sleeve. And its the only other picture I have of it other than when it was just done.

So I got this tattoo about a month and a half ago, and then had to leave for training so I could add to it (Im in the Army and stationed in Italy currently). The idea is that this is Ares the greek god of war. I want to finish it into a half sleeve. Im looking for some ideas as to what to put underneath him and on the inside of my arm. On top of him I’ll put a sun and some more clouds probably. For underneath I have two ideas but im not sure.

1. He often rode into battle with four horse so maybe those underneath him looking like they are charging into battle.

2. A huge army underneath him standing in ranks waiting to go into battle.

Any ideas are appreciated, thanks!
