The size of the letters in the upper left hand text boxes vary when looking at Figure 1 to Figure 2. The same sans-serif font appears to be used; yet, in the original figure, the letter size is larger than in the replicated figure. There is an obvious difference in photos ‘b’ as, in the original figure, the quarter is being held up to the finger. In the replicated figure, the quarter is placed on a flat surface with the finger placed to the left of it. Another difference is the actual images taken of the leaf. In Figure 1, in photos ‘c’ and ‘d,’ the leaf is not as closely seen as in Figure 2.

In the first sentence, you could modify "when looking at Figure 1 to Figure 2" to "when looking at Figure 1 in comparison/alongside Figure 2." What do you mean by "obvious difference in the photos 'b'"? It is a tad unclear. Remove the "as" in that sentence.
Suggestion
You explain the differences between the two figures nicely, but the paragraph could use an introductory sentence to explain to the reader what 'differences' and 'figures' you are talking about.

differences are explained clearly, but possibly including an introductory sentence could aid readers
