The high number of frames is only a good thing... you dont have to use all animations, and dont need to use all frames of even the animations you choose to use...by skipping every other frame example, you trade smoothness for texture-space.
I must say, yinakoSGA, the quality of your sprites is very high. Great job, and I commend your separation of the weapon from the character into layers.
I hope that eventually Spriter becomes popular enough for you to considder making Spriter optimized character animations for sale, as this would allow you to offer more animations, "infinite frames" because its tweened, and the ability to easily and completely customize the character, or create a huge variety of characters from one animation base. Please keep in mind, this is all possible with the totally free version of Spriter, and even easier with Spriter Pro. AND, even for people who want to use the sprites as full frame sprite-sheets can quickly and easily export the animations of their customized characters to any resolution and FPS that they desire.
