Nice idea, but i don;t really like the blur you applied, even if it's because you sketch really fast, but it's a good idea, so good luck!

Thanks for the input: I applied the blur because I couldn't get the edges of the hand to be smooth, and then I said I sketch fast to justify it.

great idia, nicly done

To get smooth edges you should applay a layer mask, and paint carefully wiht a smooth brush (black colour) around the hand. Good luck!

typical work for who dt have ideas!probably u new in this site good luck, and blur hand???? u should change that

Thanks isoflow: I fixed the edges and took off the blur.

The paper is laying flat,,,your index finger would be at least 4 inches above the sheet...why such a tight shad. You'd never see it, there should be no shad above the hand....and no depth to the sketch. Nice idea

From the look of the sketch the light is top right, ( though the hand doesn't justify this....it is was it is) ...longer shad at the bottom of the hand and drop a shad below the engine...bottom left . this will give the appearance of the the engine coming off the paper. Flat in background and depth in the foreground......Go for it my friend.

The blending is nice now, and the image got much better after you removed the blur!
