Yes indeed, I must agree with this. Dave's as good at self promotion as he is at painting and consequently he's become a community celebrity with a lot of people acquainted with his lighting, framing and rendering. Honestly though, the tricks he employs to get "punch" are pretty standard (RIM LIGHT!) and I feel like there's less stylistic wiggle room when rendering high fidelity materials. A lot of the cinematic blurring, blooming and colour grading could be said to be borrowed from Jason Chan (cuz he's famous!) who in turn borrowed it from someone else (who's maybe less famous or just really old). You have admitted Dave's an influence, but you are creating original artwork and to me, that's what matters. Because, at the end of the day, you are working for clients not the artistic community (though admittedly, they overlap somewhat) and there is a considerable market for this kind of work. I see your own voice in a lot of this work anyway and I'm sure it will grow stronger the more you do.
It is unfortunate, however, that the community thinks dramatic lighting of a highly detailed closeup shot is patented by Dave Rapoza
