I want someone to watch my games and tell me what I'm doing wrong

I feel like I've hit the upper limit of what my own learning experience can do for me. I know there are things I need to improve on, but I can't for the life of me figure out what they are. There's only so much one can learn on their own before they need outside advice from an unbiased observer. And, well, I'm looking for someone to be that unbiased observer. I'm not going to one of those coaching sites, simply because I'm not dedicated enough to this game to pay for something like that. However, I do genuinely want to improve, so if there's anyone out there who would be willing to help some random stranger for no reward and no logical reason, then add me in-game. Here are some requirements though:

• I want to main jungle, so I would prefer a jungle main to help me; that being said, I won't refuse someone who doesn't main jungle, since other players can have just as much to teach as jungle mains (I need help with non-jungle related things as well)

• I play a lot of Shaco, Nautilus, and Wukong; I would prefer someone who knows a lot about these champions, but again I won't refuse people who don't

• Must be genuinely good at the game; this is a no-brainer, yet quite hard to evaluate, so let's just say they need to be at least plat 3 (which is what I consider the lower limit for players "good" at the game)

• Must be patient and willing to offer CONSTRUCTIVE criticism ONLY; I don't want to hear negativity, I get enough of that in-game from my team/opponents

• I don't play ranked............ever; if this is a problem, then just move along, since I have no desire to subject myself to that toxic cesspool; I also have slight self-esteem issues, so I will probably never played ranked until I feel extremely confident in my skills

• Skype is not necessary, but I do have access to it if required

Bottom line: I'm tired of losing for reasons unbeknownst to me. Sure, I could post on the forums from now until eternity, but reading a post/guide by a knowledgeable individual and applying the principles laid out in it are two very different things. I want someone who is actively judging and evaluating my performance, not someone who is hearing about how I did through second-hand information. I'm not the kind of person who doesn't take criticism well; I'm a no-nonsense type of guy who doesn't want someone to tread lightly around the issues. If I'm doing something wrong, I want people to tell me straight up, and I'm looking for someone willing to do that.

IGN is the same as my forum name. I'm available at pretty much any time during the day. For those who understand and have been where I am now, please contact me.
