The approach here would be to either have Eiji and Ash in their exact positions and facial expressions by themselves and take whatever from the background one likes. That it is a prison setting, just Ibe there for inclusion to the couple hugging in the background, there are many ways to depict this nice moment
Ash is not trapped with you, you are trapped with him. This power shot of Ash in a well hones rampage taking out anything dangerous that looks at him funny is vital. These scenes were just one pinnacle of Ash's fighting ability as well as his awesome pose here
Everything here says so much and a good case where an appropriate title, or no title at all can make the image
This is almost as funny as when Eiji was outraged when Ash was not waking up when he was told XD
It is another unstated thing, thinking about it how awful would it be to Ash on his own, kidnapped to then find himself face to face with someone aiming a gun at you? Yes Ash is in control here, he is the antithesis of the casual danger all around and knows how to handle these awful situations, good on him. Yet this image also shows a betrayal by those in power, or shows Ash disappointed that there was no candy bar despite all his efforts XD Or maybe just a nice image to draw, the wall effects are pretty cool to note how lovely the backgrounds are, up to you!
Ultimate yes to drawing this, spotlights must be on form, only the masters could translate the glory of Ash's candy bar song onto paper themselves, Ash's mastery must be on full display!
(oh my goodness and the image title as well XD )
A drawing of a photo in an animation would be real cool! Especially this one, incredible on so many levels: it shows Ash and Eiji at ease living everyday life in quite the amazing way really, they are made for one another, in the context of the photo it's just them content and happy with everyone by themselves... since they do not matter in the frame of the image it's all about Ash and Eiji. Though that is the best lens to look through (oh that's funny, camera lens and all) it could also be sinister what with them being monitored by Blanca of all people. Still definitely a great image of them two.
The above images are just of Ash from the anime that could be drawn, with him and the effects done by pencil, colours, anything. The of course there are the ones of him in the manga, with other people, fan made visualisations of Ash with other characters. Then images of other characters!
What do you think?
