This looks like a pretty nice deck. I do have a few suggestions for you that may be of some benefit. Whenever I build a deck i always focus on the creatures first. This is because no matter what spells you may cast a creature will always be a vital tool capable of attack, defense, and battle tactics & effects. Some of your creatures have great abilities but you might want to trim some out in exchange for multiples of others. For example, blessed spirit has a good effect but you only have two enchantments in your deck. It's a good card but it'll slow your deck down because you'll be waiting to draw those two enchantments from your entire deck just to make a 2/2 into a possible 4/4. It'd make you a sitting duck.
Next is the theme that the deck is taking. The renowned creatures are excellent choices and they would work well with any exalted cards you may come across (exalted= when only one creature attacks that creature gains +1/+1 for every exalted creature that you control). This way a single creature such as your
rhox maulers who already has trample can go from being a 4/4 to being a 7/7 ( if you have 3 exalted creatures on your side of the field when it attacks). Then once it deals it's damage it'll gain it's two +1/+1 counters and by the end of the turn your
rhox maulers will be a 6/6. This combination can work with any of your renowned creatures. The exalted creatures mostly came from the SHARDS OF ALARA block and would be an excellent choice if you wanted to make a modern deck.
Lastly are the spells that you'll be casting during the duration of the match. The big downfall of creature decks is the limited protection that is offered as the creatures battle with the enemy. Adding cards such as
ranger's guile,
rootborn defenses, and
display of dominance are good additions to this deck because they provide protection for your creatures and also from other colors. Also if you wanted to stick to using the creatures and spells that make tokens the cards from the guild known as the Selesnya Conclave (From the Return to Ravnica block) are excellent at making copies of tokens and playing cards that have a large scale effect on the creatures you play.
