Well *^^* That's flattering actually. Good art takes time though. I learned that when making my fancomic which speaking of which, tomorrow night, I am doing the next page. Moreover, I have to make an ID and organize my page on DA because on Friday, my sentence is over. So the concept art will have to wait on my original story.
Oh, that was so funny thanks. While I am one of the few people who does not find Starscream's laugh really does sound like Spongebob's it does look funny when he does sound like him.
...you honestly didn't know this? YES, Tom Kenny is very versatile. He does the voice of not only Spongebob and Starscream, but on Transformers Animated he also does the voices of Jetfire, Professor Sumdac, Sari's tutor bot, and Wasp. That I can remember off the top of my head, at least.
Starscream's voice is actually very similar to Spongebob's, and it's because Tom Kenny was trying to make him sound as ridiculous and corny as his G1 counterpart.
When I first watched Transformers Animated I could not take Starscream seriously because he sounded so much like Spongebob. After a while I finally realized I wasn't supposed to, and I embraced the voice.
Skywarp is a dead ringer for Spongebob when he screams or talks in his rattly frightened voice. I could probably put voice clips of them side by side and you wouldn't be able to tell who is who.
