Right off the bat your channel header, avatar, logo and colours are great. It's also great to see you giving credit to the designer.
Viewing your channel as is shows that you have no content. I know your content exists because I clicked on 'Videos' but your home page, the first thing users see when clicking on your channel, shows nothing. You need to set up your home page so it displays your latest videos and playlists if you have any.
It's an old web design principle that applies to YouTube and any form of content creation. Back then, if users couldn't get to or see your content within 10 seconds then you've lost them forever. Nowadays, that time has been reduced to nothing. If people can't see what you have INSTANTLY then they'll find another channel. First impressions matter more than you think.
Your thumbnails are fantastic. Each series is clearly defined and consistent. I advise that you put your Sleezer logo somewhere in your thumbnails (top right hand corner perhaps?) so people know the content belongs to you.
As for the videos themselves, you're off to a great start. I'd be interested to hear your audio quality when your new mic comes in. You're definitely on the right track, you just need more content or at the very least a frequent upload schedule.

The channel link in your YTTalk profile doesn't work. I'm assuming this channel belongs to you?

I'll base my critique off of that channel.
On the computer I'm on I can hear a lot of background noise with your audio recordings. It's great that you're not blowing out the mic with plosives but I can't ignore the backgroud noise hiss. Like the other advice I have given in this thread, record 10 seconds of silence (turn mic on, don't speak, just record the natural room noise) and depending on what audio program you're using, use the noise sample to cut it out of your main recordings.
Core concept of your channel is good - reviews of cartoons and commentary on certain topics. However nothing you have visually can be attributed to you. 'Sirmel11' is written in a plain typeface and has a simple black stroke, similar to your thumbnails which uses the very meme heavy Impact font. Your channel header is a collage of anime and cartoon characters and your thumbnails are just images taken from promotional art. Nothing about any of this tells me the content is yours or belongs to you.
To top it off, the videos themselves are just the same images used for the thumbnails with audio commentary laid on top. I understand that leaving a podcast/netcast/audio commentary on while working on something else works for a lot of people. Your commentary however is short so it has no staying power like a 1-2 hour netcast.
Try to find a way to keep people visually interested in your videos - add an audio visualisation (like the old school Winamp visualisations) or change the pictures around every so often. Keeping it static doesn't hold peoples' interest visually. Also consider adding in some music in the background (in post, not while you're recording).
