really nice paintings tom! i love your style alot
a small crit on the frog, somehow the silhouette gets lost, its flowing into the background somehow, maybe you should add another light source on one side to put emphasize on the contours, plus the green of it looks really dark, maybe brighten it a bit up, i would also use brighter highlights, since you have pure white on his lip and chest
the second painting is really cool, did u draw it from life or imagination?
i am so in love with your choice of colors in the third one!!! it looks awesome some kind of pastel and oily color sheme
nice warm-cold contrast some more refined rendering and some details here and there could be good on this one...what did u paint this on? looks like a photograph underneath...
i like the last one too, but pure black in such a mass makes the pic heavy in some way, maybe use a dark blue for a color contrast or add greens, idk, i would also change the composition a bit
increase the perspective and diagonal lines much more...lol but thats some minor stuff the painting itself is really nice!
really like your stuff, you improved alot! you should definately post some more!
hope you dont mind my crits, your paintings are really good...im a bit weird with my critting behaviour

nice to see you here again mate!
