The screw and the sharpener are the same material- the sharpener is a dinky little silver metal thing. Now, that's not to say that I took that into consideration at all, I was just pointing it out. XD So, let's say the source of light were coming from behind the sharpener- which is what I was going for. The shadow it casts would then be in front of the object, and darker than the object itself? So, I should shade an amount of space in underneath/in front of the sharpener in a dark shade, which steadily lightens, right?
By the way, keep in mind that there will always be others who look at your knowledge, laugh at it, and then proceed to speak what seems like Greek for hours on end. Life's a learning process, so I can confidently say that you know everything you need to and then some. ^^" Thank you for this, by the way. I've stared at that sharpener for long enough that I actually have an accurate mental image of what the drawing should look like- now comes the transfer from my head to paper... >.>
