I see a conflict of interests here. You have a bunch of control spells for starters, which isn't a terrible thing but I think you'll definitely want to pare the list down to the best ones.
Next, you have a bunch of creatures. Control tends to not run so many, and it also tends to run creatures which give a large return on investment. Consecrated Sphinx and Snapcaster Mage would be examples.
The problem comes from dividing your board so much. Half of your deck is centered around playing creatures in the early game, and the other half needs that mana left open for instant-speed counterspells and control...
Also, you should try to stay at or barely above the 60-card mark. This will help you improve consistency. If you take playsets of 3-ofs the best cards for your deck and put them into a 60-card shell, then you're more likely to draw any given card than if you had 2-ofs in a 70-card deck.
When choosing creatures, consider what each creature does for you to determine if it deserves a place. For example, Solemn Simulacrum is land fetching, draw power, and a body for 4 mana. By comparison, Neurok Invisimancer is an unblockable 2/1 that can make something else unblockable the turn it comes in. However, nothing in your board can really deliver a large amount of damage, so Invisimancer is kind of lackluster. AEther Adept bounces threats, but you already have a bunch of cheaper instant-speed equivalents. You lose the creature for more flexibility in timing and cost.
The most important thing is whether you feel like keeping the deck standard-legal (I will only recommend cards from standard-legal sets, which are Scars of Mirrodin, Mirrodin Besieged, New Phyrexia, M12, and Innistrad) or if you feel comfortable adding other, older cards to the mix.
I would start from the instants and sorceries, since those are the most vital components to the control aspect of your deck. A simple base would be 4x Mana Leak and 4x Ponder . This will help you control most spells until the midgame and also dig through your deck to find the answer you need to any problem you have.
You might add 2x Disperse , which will help bounce any threats.
Think Twice would add some additional draw power.
For the creatures, a lot of the recommendations depend on your budget and the cards you have available. Solemn Simulacrum , Consecrated Sphinx , and Snapcaster Mage are common inclusions in a lot of control builds but they are also kind of pricey. Frost Titan is relatively easy to find in trade binders and shops, and is an inexpensive way to improve the control aspect of the deck.
The biggest thing is to not worry about cramming every good creature or every control spell into the deck. Take the best cards for your goal and make sure they work together as a deck.
